3 Reasons to Use Tab Memory Usage
Fast and lean memory calculation

This video gives you an idea of how the extension works in your browser.
With the addition of various addons and extensions in the usage of modern browsers, it is imperative that a certain tool be allocated for the specific purpose of calculating the specific units of storage that is being used in the functionality of an application. Most users are unaware of data storage issues that result from the opening of too many tabs in a single browser. Multiple tabs can now be measured for the amount of memory they consume, as Mozilla Addon store has come up with an easy solution to the problem. This solution is presented in the form of Tab Memory Usage extension, which is a fast and effective Firefox extension that displays the memory use of an individual's tabs next to the tab title. This is advantageous in the way that it allows keeping "tabs" on the amount of memory being consumed by each open window, for a further management of device storage. This extension has the ability to work out-of-the-box, with little or no settings required to set its service into action. The usage of the memory is calculated on the basis of tab components and helps prevent the Firefox browser from slowing down.
Firefox uses the built-in API to determine the amount of memory being used, which is then displayed to be managed for the optimum performance of the browser. These tab statistics can allow a user to be properly aware of the memory being consumed by each specific tab, which in turn, helps the user determine the importance of the tabs. By prioritizing windows, an individual is able to free up storage and make better decisions in their analysis.
Frequently Asked Questions
1. How does Tab Memory Usage work?
2. Why there is no memory usage indicator when a new tab opens up?
To improve performance, memory usage calculation is only triggered when a tab is refreshed or get updates. A blank tab usually uses less than a mega byte of memory and hence the extension skips blank tabs.
3. How can I download the source code for Tab Memory Usage?
To download the source code for this extension from Chrome Web Store, it is recommended to use Extension Source Downloader. With this addon, you can download the source code as a ZIP or CRX format to your machine. If you want to download the source code from the Firefox addons store, please open the firefox download link (if available) in the Firefox browser and then right-click on the - Add to Firefox - button and select - Save Link As... - item. Choose the destination folder on your machine and then save the file in XPI format. You can then rename the XPI format to a RAR or ZIP file. Some extensions may have a GitHub repo address, which you can use to download the source code as well. But, it may not be the latest version of the addon. Therefore, downloading the source code from the official web stores is the best option as it always gives you the latest version of the addon.
4. What is the meaning of badge's color in the Toolbar mode?
In the Toolbar mode, badge is color coded to have better visibility. Basically the color is gradually changed from a min to a max value (can be altered from the options page) based on the total memory usage of the tab. To calculate the percentage of memory, tab's memory is divided to 50 MBytes (consider 50Mbytes as a normal high memory usage for a webpage).
5. Where is the setting page of the extension?
Go to about:addons. Then find Tab Memory Usage add-on and select options page.
6. Is it possible to temporary deactivate the memory calculations (as of version 0.2.2)?
Yes, open Firefox addon manager, then find the extension and hit disable. You will notice the tab memory usage indicator is disappeared. To have the extension display reports again, just enable the extension one more time.
7. Can I change the position of memory indicator?
Yes, go to the options page. There are three different possibilities (as of version 0.2.2). 1) Inside: Memory usage is appended to the title of the tab. Note that
window.title can see the appended memory usage in this case. 2) Outside: Memory usage will be placed to the right of the title element just before the close button as a new element (if you have many tabs opened, maybe there would be not enough space for the title of the tab). 3) Toolbar: In this case, tab memory usage is displayed inside a badged toolbar button. For Toolbar mode, you can only see the usage of the currently opened tab.
8. In the options page, there is a minimum time interval for memory calculations. What is the meaning of this interval?
The interval indicates that memory calculation for an individual tab cannot happen more than the interval time even if memory of the tab has been changed. For the Tab Memory Usage extension to work optimally, there is a memory observer module that notifies the extension a tab requires memory calculation. The interval insures a lower bound for memory calculations of a single tab.
9. I have many tabs opened. Is tab memory going to slow down my browser?
Well, memory calculation is a pretty heavy task. That is the reason why there is a minimum time interval for memory calculations. For normal number of tabs (around 10 simultaneous tabs), the default minimum time interval is okay, however, if you have more than 10 tabs, it is recommended to prolong the minimum time interval in the options page.
10. What's new in this version?
See our version history page at the Firefox add-ons site for details about this update.
